【摘要】 在9度设防烈度下,按《水工建筑物抗震设计规范》(DL5073—2000)的标准和方法对金安桥碾压混凝土重力坝进行三维有限元动力计算,分析其地震动力响应,并按最不利原则进行静动应力组合,采用承载能力极限状态式校核其抗震强度和稳定安全。计算结果表明,金安桥碾压混凝土重力坝满足规范抗震设防要求,是安全可靠的。更多还原

【Abstract】 According to the criterions and methods given in Specifications for Seismic Design of Hydraulic Structures(DL5073-2000),the dynamic response of Jin’anqiao RCC Gravity Dam is calculated with 3D finite element method under the seismic fortification intensity of 9 degree, in which the combination of both the static and dynamic stress states is made with the principle for extreme condition, and then the aseismic strength and the seismic stability are checked with the formula for the bearing capacity under extreme condition. The result indicates that the seismic fortification requirement for the dam can be met and it is safe and credible.更多还原
